febuxostat for cerebral and cardiorenovascular events prevention study

Conditions: Hyperuricemia

Summary: the purpose of this study is to demonstrate the effect of febuxostat in preventing cerebral and cardiorenovascular events in elderly patients with hyperuricemia who are at risk for cerebral and cardiorenovascular disease.
